Asian citrus psyllid quarantine expands

Sacramento, California - A portion of Kern County has been added to an existing quarantine for the Asian citrus psyllid (ACP) following the detections of multiple ACPs in and around the cities of Bakersfield, Arvin and Taft. A total of 1,146 square miles are now under quarantine in Kern County.

The quarantine prohibits the movement of citrus and curry tree nursery stock out of the quarantine area and requires that all citrus fruit be cleaned of leaves and stems prior to moving out of the quarantine area. An exception may be made for nursery stock and budwood grown in USDA-approved structures which are designed to keep ACP and other insects out. Residents with backyard citrus trees in the quarantine area are asked not to transport citrus fruit or leaves, potted citrus trees, or curry leaves from the quarantine area.

ACP county-wide quarantines are now in place in Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara, Tulare and Ventura counties, with portions of Alameda, Fresno, Kern, Madera, Merced, San Benito, San Joaquin, San Luis Obispo, Santa Clara, and Stanislaus counties also under quarantine.

The ACP is an invasive species of grave concern because it can carry the disease huanglongbing (HLB), also known as citrus greening. All citrus and closely related species, such as curry trees, are susceptible hosts for both the insect and disease. There is no cure once a tree becomes infected, and the diseased tree will decline in health and produce bitter, misshaped fruit until it dies. In California, HLB has only been detected in 2012 and 2015 on residential properties in Los Angeles County. This plant disease does not affect human health.

Residents in the area who think they may have seen ACP or symptoms of HLB on their trees are urged to call CDFA’s Pest Hotline at 1-800-491-1899. For more information on the ACP and HLB, please visit: www.cdfa.ca.gov/go/acp.
